LT1 Starts then Dies!!! So I've read many of these and I can't figure mine out. Its a 96SS all stock. I bought it from my dad who hasn't driven it for 3 years. At first it didn't crank at all so I jumped the yellow to purple wire on the TDR. Now it runs for about 10-15 sec and dies. Ive checked fuel pressure and thats around 41psi at all times. Had the ICM checked like 16times passed every time. Checked for codes has none. I changed out all the fuel and put on new fuel filter. Please help

I think if plugs were bad it would run rough when it runs it runs great. Has great throttle response and sounds good. It acts like the key got turned off.

no security light and i checked that when it didn't crank and found it was a bad theft deterrent relay that i bypassed, also the injectors seem to stay on as the car shuts off. something is telling it to shut off the spark, can't seem to figure what sensor would shut off the spark

so i called a friends shop and they looked up common solutions to a 96 lt1 camaro that runs for 30 sec and then dies they said if fuel pressure and injectors are working then its the ecu so i replaced the ecu and still have same problem... also camaro448hp are you talking about the abs/ign relay under the hood i replaced that with no luck either, any other suggestions cause this is getting really frustrating having a car that runs great for a few seconds and then dies...

Tonight I also bypassed the VATS by using a resistor and cutting the white wires and it didn't make a difference with the resistor in or not so I'm really confused. Any ideas?
